To all avhom z't may concern:

Belt'known that I, ROBERT S. CADE, a

citizen of the United-st'ates, residing at Canton, in the count of Starkand State of Ohio, have inventec new and useful lm proyements inCombination Metal Weather- Strlps and Guides for WindoW-Sashes, of Whichthe following is a specification.

This invention relates to *combination weather strips and guides forwlndow' sashes. v

One object of the invention'isto provide sliding connections between thesashes and sides of the window frame, including spring metallic stripsacting as sliding guide members and also as sealing devices to'exclude Afurther object of the lnvention is to provide metallic guiding andsealing strips which exert spring pressure on the guide of the frame,whereby'rattling of thesashes will be prevented, and which strips 'rnaybe adjusted to vary their spring pressure.

A still further object of the invention is to provide a guideconstructionwhich simplifies the general construction of the windowframe, and permitsof the use of either wood or metal stop strips,as'desir-ed. V v

' A stillfurther object of the invention is to provide strips forefliciently closing the joints between the meeting rails of the sashesand between the sashes and the lintel V and sill of the windowjframe.

A still further object of the invention is to provide a structure of thecharacter stated which greatly simplifies the manufacture of windowframes and thesashes therefor, and by the use of whichthe usual'guidestrips and beads commonly employed in such frames are eliminated. 1 r 7With these objects in view, together with others which will appear asthedescription the invention resides in the novel as will be describedmorefully hereinafter, illustrated in the drawings, and particularlypointed out in the claims. In the drawings Figure lis a view inelevation of a window frame and sashes embodyingmy invention,

coextensive with the said sides.

'pair of spaced I ,Fig. 4 is a perspective view showing'in detal theconstruction of one of the spring The invention, generally stated,resides in providing the inner faces of the side members of the windowframe with spaced longitudinally disposed parallel grooves or channelsarranged inpairs, the grooves or ,channelsjof each pair being spacedapart a "distance substantially equal to or slightly greater than thewidth of the stiles of the sashes, and resilient metallic plates orstrips are secured to the stiles and engage in the said grooves and'frictionally bind with the walls thereof. While the frictionalengagement of these strips is suflicient to exclude the passage of air,dust, etc. through the channels, it is not sufiicient to interfere withthe free sliding movement of the sashes.

These strips, also, possess sufficient strength and rigidity to maintainthe sashes in proper 7 position within the frame, so that the said"sashes are firmly held against displacement. Thefinvention furthercomprehends the'use of similar means .at the top of the window frame, atthe bottom thereof, and at the meeting rails of the sashes to preventthe through the window frame In the vention is illustrated as applied toa window drawings, 5 indicates the sides of i the window frame, 6 thelintel thereof and 7 the sill. In the present instance the inframeformed of cement or concrete, and the sides 5., and'lintel 6 are of woodand are firmly secured to the sides and top of the frame. Thisparticular construction and method; of forming} the frame need not beadhered to in carrying out the invention, as

the-ordinary wooden frame may equally as well be used.

The inner faces of the sides 5 of the frame are provided with spacedchannels or grooves 8, the same being parallelto each other and i Thegrooves are arranged in pairs, a pair ofeach of said rooves beingprovided foreach sash. The lintel 6 of the frame is provided with aparallel grooves extending from one'end to the other thereof, and thesegrooves communicate at their ends with the represents the upper sash.These sashes may be of the usual well known construction,

and the stiles thereof upon both their inner and outer faces areprovided with metallic strips or plates 11. These plates areof equallength'with'thestiles, and are secured to the latter near their inneredges by screws or struction, in addition to forming an air seal,

strengthens the structure and relievesto a great extent the strain uponthe retain ng screws 12.

V The outer edges of the strips or plates extend into the grooves 8, andthe portions of these strips which are inclosed by the grooves are bentbackwardly upon themselves and are rounded as at 13to enable the saidplates to frictionally engage with bath 3 reason of this doubleengagement of the strips with the walls defining the grooves, a doubleairseal is provided, and by doubling the plates upon themselves the sameare strengthened or reinforced. As the portions of the strips extendinginto the grooves are round, there will be a comparatively small amountof contacting surface between the strips and the channel walls, andwhile this. area of contact is sufficient to exclude the passage ofairfthrough the channels, it isnot suflicient to create such friction asto retard or impair the free movement of the sashes. The degree ofpressure of the bent'portions of the strips upon the channel walls maybe increased by expanding the bent portions of the strips by theinsertion of a pointed or flat instrument therein. 7

The meeting rails of the sashes 9 and 10 are cut so as .to snuglyinterfitwhen the sashes have been moved to closed position, and ametallic strip 14 is secured to the upper surface of the sash 9 so as toextend over the, joint between the rails when the sashesare closed. Thisstrip is applied to the rails by driving screws or tacksthrough one edgethereof, and the free end of the strip is bent upon itself as at 13similarly to portions of the strips'upon the nel is provided with abeveled orinclined wall to be engaged by a similar inclined surface atthe lower edge of the said bottom rail. To exclude air, dust, etc.,gaining access to the room below this bottom rail, a

resilient metallic air excluding strip 15 is v employed. This strip, inthe present instance, is fastened to the inclined surface of the latterislowered will cause this resiliency bent'portion to tightly seal thejoint between the sill and the sash. 7

In order that 'air will be prevented passing into the room above theupper sash when the latter is at the limit of its upward movement,strips16 are used.- These strips are similarin construction to thoseupon the stiles of the sashes, and are arranged one upon each face ofthe top rail of the upper sash 10; The free edges of these plates orstrips enter the grooves 17 in the lintel 6 when the sash isin raised orclosed position;

While the friction'between the various metallic plates and the walls ofthe grooves which theyenter need only be sufficientto exclude thepassage offair, dust, etc., around the edges of thesashes, still thisfriction of adjustment, thus eliminating the use of monly employed forthis purpose. 7

From the foregoing it is obvious that I have provided a windowconstruction such as will enable the sashes to slide smoothly and evenlywithoutthe use of the beading and ribs heretofore used for theconfinementand guidance of these sashes. At the same time, air will beprevented passing around the edges of the sashes when the latter havebeen moved to closed position, as a double air seal is provided at eachedge of the stiles, upon theupper rail of the top sash, at the meetingrails of the upper andlower sashes and at the juncture of the bottomrail of the lower sash with the sill. The. strips 01 plates areof'simple and inexpensive conwindow weights 1 and other "devicescomstruction and may be easily and quickly ap- 7 plied to and removedfrom the sashes without the use of specialskill or tools.

While the above is 'a description of the preferred embodiment of theinvention, it is obvious that the invention is not necessarilyrestricted'thereto, as various changes in the minor, details ofconstruction of the strips and sashes may be made without departing fromthe invention as defined by the claims.

I claim e 1 1. The combination with a window frame including a pair ofsliding sash sections, of

relative narrow grooves being formed in the opposed faces of thevertical memberssof the frame, one of said grooves being vdisposed atopposite sides of each of said sash sections andhaving their inner wallsin alinement with the corresponding'faces of the latter, and fiatmetallic strips secured on opposite sides of each of said sash sectionsand projecting into said grooves in Cantacting relation with the innerwalls thereof, said metallic strips having their edge portions withinthe grooves formed to provide folded portions disposed in contactingrelation with the outer walls of the latter.

2. The combination with a window frame, including an upper sliding sashsection and a lower sliding sash section, of relative narrow groovesbeing formed in the opposed faces of the vertical members of the frameand coextensive therewith, one of said grooves being disposed atoppositesides of each of said sash sections and having their inner wallsdisposed in alinement with the corresponding faces of the latter, andflat metallic strips secured on opposite sides of said sashes andprojecting into said grooves in contacting relation with the inner wallsthereof, said metallic strips having their opposite edges reverselyfolded to provide inturned portions, one of said inturned porstrips isretained firmly in contact with the r alining surface of said sashes andthe inner.

walls of said grooves.

In testimony whereof I aflix my signature.

ROBERT soADE.
